Vehicle Drive Systems

With the rapid development of the electric vehicle industry in recent years, drive motor technology has also made significant breakthroughs. Electric vehicles place stringent demands on drive motors, including high speed, high power density, lightweight design, miniaturization, and high reliability. Against this backdrop, high-performance insulation materials have become a key foundation for improving motor reliability and power density, and a crucial support for the continued development of advanced motor technologies such as high-frequency, high-voltage, high-temperature, and internal oil-cooled motors.

Electric vehicles, which use electricity as their primary power source, mainly include core components such as the battery and management system (BMS), drive motor and control system, vehicle management system (VMS), and the vehicle body. Among these, the motor, as a key power component of new energy vehicles, directly impacts the green and sustainable development of the entire industry through technological innovation.

Currently, motor technology is advancing comprehensively towards permanent magnetization, high speed, oil-cooled flat wire, integration, miniaturization, lightweighting, high efficiency, and high power density, and has achieved a series of significant advancements. In the motor insulation stage, the core objective is to achieve reliable isolation between conductors and between conductors and the iron core through high-performance insulation materials.
